>From looking at it, you're trying to do a loop with only one line of code,
which, without closures is going to be pretty tricky.
I would just do it as (this is typing on the fly, so you may get some
errors):
<cfloop collection="#filter#" item="key">
<cfset text = replaceNoCase(text, "[" & key & "]", filter[key]) />
</cfloop>
And be done with it.
You could get fancy and use a StringBuffer/Builder if you wanted to, but for
the number of lines of text, it may not be necessary.
